thermal discomfort

With the goal of increasing building flexibility and reducing energy use, yet ensuring IAQ, the feasibility of natural ventilation in a building in Oslo is studied. However, the use of direct outdoor air poses some challenges in the Norwegian cold climate, particularly the risk of thermal discomfort due to draught and low local temperatures. The goal of this paper is to study the most suitable solution to avoid draught in cold climates while maintaining the required airflow rates.

This work deals with experimental investigations on human reaction to local air movements of people in global thermal comfort, performing light activity. An analysis on draught risk was developed comparing the results with previous research findings on human response to draught. The intensity of air velocity, in terms of mean value and relative turbulence, was referred to the level at which normally clothed people could perceive and feel air movements behind the neck, in global neutral thermal condition.
